With the Laser Tower, visitors move mirrors to bounce laser beams through a semi-dark environment. Bursts of mist reveal the location of the beams and guide visitors as they create structures with light.

Visitors notice that a laser beam reflected off a mirror acts as an optical lever, making small vibrations in the mirror highly visible at a distance. Spinning mirrors mounted near the top of the structure reflect cones of laser light through the mist and onto the fabric structure of the exhibit.
